For those questioning Utah's core or 'blowing it up' -- as well as those hoping to trade for Gobert -- I think the point is that their core IS Gobert, Lyles, Hood, Exum, and Burks.
The Jazz are not going to be luxury tax payers, especially if they're not clear cut champ contenders. Lyles, Hood, Burke, and Exum have all shown very good promise and will need to be paid. Gobert is going to command the max. He and Favors have made the best of it, but are not a great fit. Hood has also come to duplicate the game of Hayward quite a bit. Meanwhile, the Jazz are arguably the NBA team most in need of a quality PG.
So while this is obviously an admission that they're not ready to contend, this is not the Jazz blowing it up. It's about them structuring their asset pool to appropriate align with the rise of Golbert, Exum, and in this case, Smart and this year's BKLN pick.
